Application filed February 28,1906. Serialhlo. 803,494-

of Missouri, have invented certain new and useful Improvements inGas-Producers, of which the followin is a specification.

The invention re ates generally to gas-prbducers, but more particularlyto devices for ro feeding fuel to the combustion-chamber thereof; and itconsists, essentially, of the novel construction of the several partsand their peculiar arrangement and COIIlblIlfim tion, as will behereinafter fully described in this specification and briefly stated inthe claims.

The main' objects of the invention are, st, to providea mechanism foruniformly a d evenly distributing the fuel to the combustion-chamber,second, to provide means for protecting the fuel-distributing mechanismfrom the intense heat generated in said combustionchamber, and, third,to simplify and cheapen the cost of construction of 2 5 said mechanismWithout impairing its dura bility and usefulness in operation.

Other objects of the invention will become ap arent upon a fulldisclosure thereof. n the drawings, Figure 1 is a vertical cen- 0' tralsection of my improved feeding mechanism Fig. 2, a horizontal section online 2 2 of Fi 1; Fig. 3, a to. plan of the rotatable fu el-d'stributer,and l i 4 a similar view of the fuel-distributing disi.

Referring to the several views, the numeral 1 indicates the upperportion of a gasproducer, and 2 thecombustion-chamber thereof. Theproducer may be of any approved or well-known construction and isprovided with a metallic top plate 3, having a central ipening 4,surrounded by a flange or collar 5.

he top plate is provided with the usual stoker-openin s 6.

Secured to t e top plate is an outer flanged collar 7, and secured tothe collar 5 of said top plate is an inner collar 8, the space betweenthe two collars forming a water seal 9. A water-chamber 10 is formed uon the top plate by means of the outer col ar 7 and a flanged collar 11,the latter being provided with an overflow-pipe 12.

Mounted upon the top plate within the water seal 9.is a fuel-magazine13, provided with a supply-opening 14, controlled by the usual damper orvalve 15.' Secured within the fuel-magazine is a hopper 16, having adelivery-opening 17 for the passage of the fuel. The fuel-magazine isprovided with a downwardlyextending central tube or sleeve 18,'the lowerend of which rests upon a bearing hub or block 19, supported byupwardly-projecting arms2'0 20, secured to t e wall of thefuel-magazine. Within the tube or sleeve 18 and having bearings in thehub 19 and a block 21 is a tubular shaft 22, provided at its upper endwith a beveled gearwheel 23, supported by-and rotatable upon aball-bearing in the block 21, as shown in Fig. 1, and carrying near itslower end a fuel-distributing disk 24, having upwardly and outwardlyprojecting arms 25, extending up into the opening 17.0f the fuel-hopper16, said armsserving to keep the fuel constantly in motion and preventclogging around the shaft and on the disk. The upper surface of thedistributing-disk is slightly inclined from its center toward its outerperipheral edge, so as to facilitate the distribution of the fuel to thedistributo.r,"to be hereinafter described. Secured to the extreme end ofthe tubular shaft is a feeder 26, consisting of a plurality of curvedarms or blades 27,1'adiating from a central hub.

Supported upon legs 28 is a bearing-block 29, and journaled in saidblock and passing through the tubularshaft is a shaft 30, provided atits upper end with a beveled gearwheel 31, supported by and rotatableupon a ball-bearing in said block 29 and carrying at its lower end adistributor 32. The distribute'r 32 is composed of a hopper 33, having adouble bottom spaced apart, the under bottom being formed with anupwardl -ex-- tendin flange 34 to provide a water-c amber 35 eneath andaround the upper bottom of the distributer, so as to protect the samefrom being overheated. Both bottoms are provided with a plurality ofwalled openings 36, and bolted to the under'bottom in line with saidopenings is a plurality of eculiarly-sha ed chutes or tubes 37, whicdistribute t 1e fuel in the combustion-chamber.

These chutes or tubes are so curved that the fuel will be distributedfrom the center outward toward the wall of the combustionchamber.Projecting inwardly from the upper edge or rim of the distributer-hopperis a the top of the fuel-magazine, is'a vdrlvingshaft 40, carrying atone end a beveled pinion 41, meshing with the gear-wheels 23 and 31 andreceiving power from any suitable source.

Slidable in suitable bearings secured to a bracket 42, secured to theinner wall of the fuel-magazine, is a scraper 48, the outer end of whichprojects through an opening in the wall of said magazine, so as topermit of the scraper being operated to scrape or clean the uppersurface of the fuel-distributing disk 24,

which can be readily accomplished by setting 5 the disk in operation andgradually pushing hole 45, and as the water falls from saidoverflow-hole it will be conductedinto the water seal away from thebottom of the chamber.

In operation the fuel is delivered through the supply-opening to themagazine, the direction assumed b the fuel being indicated by the dottedline a. As the fuel passes from the hopper 16 it is caught by the armsof the revolvmg distributin -disk 24 and laid upon said disk substantialy as indicated by the dotted line b. The fuel is thrown from thedistributing-disk into the distributer-hoppeer and fed, through theopenings 36, into the chutes or tubes 37, which by reason of theirpeculiar shape distribute the fuel uniformly and evenly throughout thecombustion-chamber, said fuel being delivered as indicated by the dottedlines 0. It will be obvious from the arrangement of the drivingear thatthe distributingdisk and the eeder-arms will be rotated in a directionopposite to that of the distributer 32, so that the feed of the fuelinto the distributing chutes or tubeswill be rapid and uninterra ted.

n feeding fuel to the roducer it is important that'the 'fuel shouid beuniformly distributed and that it be fed uninterruptedly. In order toaccomplish these, objects, it is necessary tov distribute the fuel overas much of the surface of the distributer as possible, and this Iaccomplish by arranging below the exit of the fuel-hopperlfi therotatable dis,- tributin -disk 24. This disk forms an imortant eature ofIn invention, as by its use am able to distri ute thefuel upon the outerportion of the surface of the distributer 32, W ich is of a much greaterdiameter than the e 't of the fuel-hopper 16 and not all at the centerof said distributer, as would be the case if the distributing-disk weredispens'ed with, in which case it will readily be seen'that the fuelwould pass through the exit of the fuel-hopper 16 down upon thedistributer in a pile around the'sleeve 22. Such a contingency wouldnecessarily render the operation of the feeder 26 exceedingly difficult.

In practice it is of the utmost importance that the fuel be distributedover the surface pf the distributor 82' from the center to the wouldhave to be rotated at a much greater speed than the distributer.

It will be noted that all of the parts of the mechanism subject to theintense heat of the combustion-chamber are protected by the water sealand the water-chambers, into which a constant flow of water rnay bemaintained, and that the operating-shafts are protected from the fuel inthe magazine by the tube or sleeve 18.
